T0 to whom it may concern.-

Be it known that I, FRIEDRICH WANGELIN, 'a subject of the King of Saxony, residing at Dresden, Germany, have invented certain new and useful Improvements in Flushing Apparatus for Water-Closets, (for which I have obtained Letters Patent in Germany,No. 92,896, dated April 30, 1896; in Austria, No. 46/2200, dated June 2, 1896; in Hungary, No. 6,850, dated May 18, 1896; in Switzerland, No. 12,499, dated May 13, 1896; in France, No. 256,391, dated May 16, 1896; in Belgium, No. 121,416, dated May 18, 1896, and in Great Britain, No. 10,139, dated May 12, 1896,) of which the following is a full, clear, and exact description.

The present invention relates to a flushing device for water-closets and the like, and has for its object to bring about an efficient flushing by suddenly discharging the whole mass of water by upsetting the collecting-tank, the inlet-valve being closed gradually and without shock. For this purpose there is pivoted in a fixed tank a second trough-like. tank, which when filled to a certain point becomes top-heavy and overturns. When the apparatus is next used, this pivoted tank is raised by means of a device operated by hand or connected with the seat from its overturned vertical position into its horizontal position for the purpose of being filled again, the closing-lever of the inlet-valve being'at the same time turned so that the latter is opened. -As soon as the level of water in the inner pivoted tank rises to a certain height this tank becomes top-heavy and is again overturned. During the filling of the tank a vessel attached to one arm of the valve-closing lever is also filled with water, and thus becomes heavier than the balance-weight on the other arm of the lever. The contents of this vessel are, however, gradually discharged through a small opening, and owing to its slowly-decreasing weight the balance-weight gradually sinks, so that the balance-lever turns very slowly and the valve is closed, not suddenly, butsoftlyandwithoutanyshock. Both tanks, as well as the vessel, remain empty when not in use, so that the apparatus cannot be damaged by frost.

In the accompanying drawings, Figure 1 shows, by way of example, one construction of the device according to the present inven tion in longitudinal section, Fig. 2 in plant, and Fig. 3 in cross-section. The inner pivoted tank is in the position occupied when it has opened the valve by raising the balanceweight and turning the closing-lever. The dotted lines in Fig. 3 show the tank in its overturned position. Figs. 4 and 5 are perspective views, partly in section, of the whole apparatus, together with the disengaging device operated from the seat, Fig. 4 showing the tilting tank raised, asduring the filling operation, and Fig. 5 showing it overturned. Fig. 6 is a detail of a ratchet device for the operating-lever.

In the outer tank 19, provided with a discharge-pipe a, there is supported on pivots c a tank d, which in its overturned position is prevented by a spring 6 from oscillating. The inlet-valve f is opened and closed by means of a hinged finger g on a double-armed lever g. To the latter there is attached at one end a hollow vessel h, having a narrow opening or perforation h in the bottom, and at the other end a balance-weight 70, whose adjustable arm or, stud z' engages with the edge of the tilting tank d.

By depressing the movable seat or by pulling by hand the .tilting tank (1 is brought, by means of a cord or otherwise, from the position of rest seen in dotted lines, Fig. 3, and in full lines, Fig. 5, into the horizontal position, Figs. 1 and 4, and by striking its edge against the arm 41 raises the balance-weight 7c and turns the lever g, which thereupon opens the inlet-valve f. When the Water admitted has risen in the tank at so high that the vessel h is completely filled, the limit of filling the tank cl is also reached, and the latter, owing to its peculiartrough-like shape, becomes topheavy and overturns, the whole of its contents being discharged into the outer vessel 5 and into the discharge-pipe a, The vessel It is emptied during this time through its perforated base, and as the weight of this vessel it decreases so the balance-weight 7c sinks and slowly brings the lever 9 into the closing position for the inlet-valve.

The tank (1 remains in the upturned position until it is brought into a horizontal po sition, as by hand'or automatically from the seat. Figs. 1 and 5 show such an automatic bell-crank lever m, to which lever 12 is attached, the lower end of the chain, cord, or the like depending from the tank (Z.

When not in use, the back part of the frame I Zis kept down by weights 19, secured to it, the

upper part (1 projecting upward, in consequence of which the closet-seat, which is usually pivoted, is slightly raised. By depress ing the seat the frame Z swings upward, passing the lever m,which is movable upward and remains at the top during the time that the seat is depressed. As soon, however, as it is released the frame I again falls downward, striking the upper arm of the lever m, which is not movable downward, and depresses it and the lever 91, connected to it, so that the tank 61 is brought by the cord 0 into its horizontal position and filling takes place.

Instead of the pivoted lever it any other equivalent device may be used.

To prevent the valve from prematurely closing, there is arranged on one side wall of the outer tank I; a ratchet device 7, Fig. 6, in

M such manner that its toothed face holds the operative lever g in the open position which .it is caused to occupy by the rising of the tilting tank d until this ratchet device 0" is released by the tank d striking in overturning against the projection r, Fig. 6, dotted. In a similar manner the valve f may be prevented from opening too early by means of a correspondingly-acting device.

I claim-- 1. The combination with a tank, and a discharge therefor, of a vessel pivotally mounted within the tank and adapted to overturn when filled with water to a certain height, a pivoted lever, a vessel carried thereby, pipes adaptedto discharge Water into the vessel carried by the lever and into the tank, a valve control ling the flow of water through said pipes, said valve being operated by the lever when the latter is tilted in one direction, the said lever being adapted to be operated by the pivoted vessel when the latter is turned to bring it to a horizontal position to effect the opening of the valve, all as and for the purpose specified.
